A new trailer broadcast during a Nintendo Direct last week showed Mario shirtless-and people had a lot to say about that. Super Mario Odyssey launches on October 27. By comparison, other first-party games on Switch are also pretty small, with Arms coming in at 2.2 GB and Splatoon 2 at 3.1 GB.Īnother point of comparison that Nintendo Everything mentions is that Super Mario 3D World, the last 3D Mario game for a home console, was 1.7 GB on Wii U. This is according to a post on Nintendo's Japanese store. According to Nintendo Everything, the file size is only 5.7 GB for the digital version. The file size for the hugely anticipated Nintendo Switch game Super Mario Odyssey has been revealed-and it's not as big as you might expect.
